Comedian Tiffany Haddish's white Alexander McQueen gown became the centerpiece of her opening monologue on ‘SNL,’ as she admitted to wearing it again and again. "I wore it on the red carpet for ‘Girls Trip,’” she said. “and my whole team, they told me ‘Tiffany, you cannot wear that dress on ‘SNL’. You already wore it. It’s taboo to wear it twice,’ and I said ‘I don’t give a dang about no taboo. I spent a lot of money on this dress. This dress cost way more than my mortgage.’”
